Manufacturer reserves the right to discontinue, or change at any time, specifications or designs without notice and without incurring obligations.Catalog No. 04-53190062-01 Printed in U.S.A. Form 19/23-9SS Pg 1 6-19 Replaces: 19/23-5SSStart-Up and Service InstructionsSAFETY CONSIDERATIONSCentrifugal liquid chillers are designed to provide safe andreliable service when operated within design specifications.When operating this equipment, use good judgment andsafety precautions to avoid damage to equipment and prop-erty or injury to personnel.Be sure you understand and follow the procedures andsafety precautions contained in the machine instructions, aswell as those listed in this guide.DANGERFailure to follow these procedures will result in severe per-sonal injury or death.DO NOT VENT refrigerant relief devices within a building.Outlet from rupture disc or relief valve must be vented out-doors in accordance with the latest edition of ANSI/ASHRAE15 (American National Standards Institute/American Societyof Heating, Refrigerating and Air-Conditioning Engineers)(Safety Code for Mechanical Refrigeration). The accumula-tion of refrigerant in an enclosed space can displace oxygenand cause asphyxiation.PROVIDE adequate ventilation in accordance with ANSI/ASHRAE 15, especially for enclosed and low overheadspaces. Inhalation of high concentrations of vapor is harmfuland may cause heart irregularities, unconsciousness, or death.Intentional misuse can be fatal. Vapor is heavier than air andreduces the amount of oxygen available for breathing. Productcauses eye and skin irritation. Decomposition products arehazardous.DO NOT USE OXYGEN to purge lines or to pressurize amachine for any purpose. Oxygen gas reacts violently with oil,grease, and other common substances.DO NOT USE air to leak test. Use only refrigerant or drynitrogen.NEVER EXCEED specified test pressures. VERIFY theallowable test pressure by checking the instruction literatureand the design pressures on the equipment nameplate.DO NOT VALVE OFF any safety device.BE SURE that all pressure relief devices are properly installedand functioning before operating any machine.RISK OF INJURY OR DEATH by electrocution. High volt-age is present on motor leads even though the motor is not run-ning when a solid state or inside-delta mechanical starter isused. Open the power supply disconnect before touchingmotor leads or terminals.WARNINGFailure to follow these procedures may result in personalinjury or death.DO NOT USE TORCH to remove any component. Systemcontains oil and refrigerant under pressure.To remove a component, wear protective gloves and gogglesand proceed as follows:a. Shut off electrical power to unit.b. Recover refrigerant to relieve all pressure from systemusing both high-pressure and low pressure ports.c. Traces of vapor should be displaced with nitrogen andthe work area should be well ventilated. Refrigerant incontact with an open flame produces toxic gases.d. Cut component connection tubing with tubing cutter andremove component from unit. Use a pan to catch any oilthat may come out of the lines and as a gage for howmuch oil to add to the system.e. Carefully unsweat remaining tubing stubs when neces-sary. Oil can ignite when exposed to torch flame.DO NOT USE eyebolts or eyebolt holes to rig machine sec-tions or the entire assembly.DO NOT work on high-voltage equipment unless you are aqualified electrician.DO NOT WORK ON electrical components, including con-trol panels, switches, starters, or oil heater until you are sureALL POWER IS OFF and no residual voltage can leak fromcapacitors or solid-state components.LOCK OPEN AND TAG electrical circuits during servicing.IF WORK IS INTERRUPTED, confirm that all circuits arede-energized before resuming work.AVOID SPILLING liquid refrigerant on skin or getting it intothe eyes. USE SAFETY GOGGLES. Wash any spills from theskin with soap and water. If liquid refrigerant enters the eyes,IMMEDIATELY FLUSH EYES with water and consult aphysician.NEVER APPLY an open flame or live steam to a refrigerantcylinder. Dangerous over pressure can result. When it is neces-sary to heat refrigerant, use only warm (110°F [43°C]) water.DO NOT REUSE disposable (nonreturnable) cylinders orattempt to refill them. It is DANGEROUS AND ILLEGAL.When cylinder is emptied, evacuate remaining gas pressure,loosen the collar, and unscrew and discard the valve stem. DONOT INCINERATE.CHECK THE REFRIGERANT TYPE before adding refriger-ant to the machine. The introduction of the wrong refrigerantcan cause machine damage or malfunction.(Warnings continued on next page.)19XRV, 23XRVwith PIC III/PIC 6 ControlsEaton LCX9000 VFD Option
